1. Clamping ring
2. Junction box

The transmitter is installed remotely from the sensor. The 9-wire connection between the sensor and transmitter must be field wired. Power supply and I/O must be field wired to the transmitter. The sensor connection is in the junction box.

Installation checklist

• Safety messages are provided throughout this content to protect personnel and equipment. Read each safety message carefully before proceeding to the next step.
• When choosing a location for components, refer to the following guidelines:
  • See the sensor installation manual for information on locating the sensor with remote-mount or extended-mount electronics.
  • Do not install a component in a location where its temperature, humidity, or vibration limits will be exceeded.
  • Maximum distance between components depends on the wire size, the wire type, and the power supply. Ensure that sufficient power is supplied to the transmitter terminals.
• If you plan to mount the transmitter in a hazardous area:
  • Verify that the transmitter has the appropriate hazardous area approval. Each transmitter has a hazardous area approval tag attached to the transmitter housing.
  • Ensure that any cable used between the transmitter and the sensor meets the hazardous area requirements.
• Verify that you have the appropriate cable and required cable installation parts for your installation. For wiring between the transmitter and sensor, verify the maximum cable length does not exceed 60 ft (20 m).
• The transmitter can be mounted in any orientation as long as the conduit openings do not point upward.
  
  Installing the transmitter with the conduit openings or transmitter display facing upward risks condensation moisture entering the transmitter housing, which could damage the transmitter.
• Any fittings, adapters, or blanking elements used on either conduit entries or threaded joints that are a part of flame proof joints must comply with the requirements of EN/IEC 60079-1 & 60079-14 or CSA C22.2 No 30 & UL 1203 for Europe/International and North America respectively.
  Only qualified personnel can select and install these elements in accordance with EN/IEC 60079-14 for ATEX/IECEx or to NEC/CEC for North America.
• To prevent conduit connectors from seizing in the threads of the conduit openings, apply a conductive anti-galling compound to the threads, or wrap threads with PTFE tape a minimum of two wraps per standard installation practices.
  Wrap the tape in the opposite direction that the male threads will turn when inserted into the female conduit opening.
• To maintain the Ingress protection thread sealant, a sealing washer, or O-ring must be applied.
  • For Zone 1 applications thread sealant must also comply with the requirements of EN/IEC 60079-14 and thus must be non-setting, non-metallic, non-combustible, and maintain earthing between the equipment and conduit.
  • For Class I, Groups A, B, C, and D applications thread sealant must also comply with the requirements of UL 1203/CSA C22.2 No. 30.
• Minimize the amount of moisture or condensation inside the transmitter housing. Moisture inside the transmitter housing can damage the transmitter and cause measurement error or flow meter failure. To do this:
  • Ensure the integrity of all gaskets and O-rings
  • Install drip legs on conduit or cable
  • Seal unused conduit openings
  • Ensure that all covers are fully tightened
• Mount the meter in a location and orientation that satisfies the following conditions:
  • Allows sufficient clearance to open the transmitter housing cover. Install with 8–10 inches (200–250 mm) clearance at the wiring access points.
  • Provides clear access for installing cabling to the transmitter.
  • Provides clear access to all wiring terminals for troubleshooting.

Maximum cable lengths between sensor and transmitter

The maximum cable length between the sensor and transmitter that are separately installed is determined by cable type.

Cable type	Wire gauge	Maximum length
Micro Motion 9-wire remote mount	Not applicable	60 ft (18 m)

Powering up the device

The transmitter must be powered up for all configuration and commissioning tasks, or for process measurement.

Procedure

1. Ensure that all transmitter and sensor covers and seals are closed.
   
   To prevent ignition of flammable or combustible atmospheres, ensure that all covers and seals are tightly closed. For hazardous area installations, applying power while housing covers are removed or loose can cause an explosion.
2. Turn on the electrical power at the power supply.
   The transmitter will automatically perform diagnostic routines. During this period, the Warming Up alert is active. The diagnostic routines should complete in approximately 30 seconds.

Postrequisites
Although the sensor is ready to receive process fluid shortly after power-up, the electronics can take up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if power has been off long enough to allow components to reach ambient temperature, allow the electronics to warm up for approximately 10 minutes before relying on process measurements. During this warm-up period, you may observe minor measurement instability or inaccuracy.

Configuring the unit with Guided Setup

At initial startup of the transmitter, click the right arrow for the Menu option to access Guided Setup. This tool guides you through basic configuration of the transmitter. The guided setup allows you to upload configuration files, set the transmitter display options, configure channels, and review sensor calibration data.

Procedure
To access the guided setup screen from the display main menu, go to: Startup Tasks Guided Setup.

Using the display controls

The transmitter display interface includes a display (LCD panel) and four capacitive buttons – left, up, down, and right arrow keys – used to access the display menus and navigate the display screens.

Procedure

1. To activate a capacitive button, press the desired button that is designated with arrows (up, down, left, and right).
   You can activate the capacitive button through the lens. Do not remove the transmitter housing cover.
   
   The transmitter only detects one button selection at a time. Be sure to press your thumb or finger on a single capacitive button.
   
   Proper finger positioning for activating a capacitive button
2. Use the arrow indicators on the display screen to identify which capacitive button to use to navigate the screen (see examples 1 and 2).
   
   When using the arrow keys, you must first activate the capacitive button, then release the same button by removing your finger from the glass to move up, down, right, left or to make a selection. To enable auto-scroll when navigating up or down, activate the appropriate button and continue to hold for one second. Release the button when the desired selection is highlighted.
   
   Example 2: Active arrow indicators on the transmitter display

Configure the display backlight
By default, the backlight is set to OFF. The backlight requires an additional 1V in voltage over no backlight.
Procedure
To configure the backlight, select Menu Configuration Display Settings Backlight.

Communicating with the unit

Use either the HART terminals connected to ProLink III or Trex unit to download or upload data from/to the transmitter, because the service port is for factory use only.

Procedure

1. To connect to the transmitter terminals or to the HART connection posts:
   1. Remove the transmitter end-cap.
   2. Attach the leads from the Field Communicator to terminals 1 and 2 on thetransmitter, or to the HART connection posts, and add resistance as required. The Field Communicator must be connected across a resistance of 250–600 Ω.
      Tip
      HART connections are not polarity-sensitive. It does not matter which lead you attach to which terminal.
